What causes tooth decay Tooth decay is mostly caused by consuming foods containing sugar. The Plaque (sticky film of bacteria) forms constantly on your teeth, when you eat foods containing sugar. The bacteria in plaque produce an acid every time you eat sugary food, which attacks your teeth enamel. The plaque always stays close to your teeth and keeps the acid close too, because of it’s stickiness. 3
